The Forgotten System

In any system design project there are always three systems of importance. The first of these is what we call the system of interest or the solution system. That is the system we intend to design. (Note: For the purposes of this discussion, the name “system of interest” may be …

The Importance of Architecting our Modeling Environment

Systems engineers and systems architects have many architectures of which they need to be aware: there’s the architecture of the system-of-interest (or system under design), the architecture of the larger system in which the system-of-interest must operate (the context system), and the architecture of the enabling system (the enterprise or …

Four Qualities of Good Models

Although modeling has always played a role in engineering, it has become a central focus with the advent of model-based systems engineering. While we as engineers are focused on engineering and building systems, sometimes the topic of modeling, as both an art and a science, still gets short shrift. If …

Modeling SysML Blocks in GENESYS: Part II

Last week, in Part 1 of this series, I described how GENESYS displays SysML block features in compartments on block nodes. This week I’ll continue the discussion and describe how GENESYS deals with the SysML relationships of composition, references, generalization, and dependencies on a Block Definition Diagram, or BDD. Blocks …
